Billy Mays, who took the art of the TV sales pitch to a new level, died of an heart attack Sunday morning, Florida authorities close to the situation revealed.
A medical examiner in Florida says Mays showed no evidence of head trauma, despite being struck on the head on board an airliner that made a rough landing.
That flight took place on Saturday night.
The TV advertising guru arrived home safely, despite the difficult landing, but Billy Mays was found dead early Sunday morning at his Tampa house.
Preliminary autopsy results show that Mays suffered from hypertensive heart disease, Hillsborough County Medical Examiner Vernard Adams said.

Toxicology and tissue tests will take several weeks before a final cause of death is issued, he said. But the autopsy showed no evidence of trauma to the head, either external or internal, despite Billy Mays hitting it on the plane.
The autopsy showed that Mays' heart was heavier than normal because the left ventricle had enlarged, a symptom of heart disease, Adams said, also noting that investigators had ruled out prescription drug abuse as a cause of his death.
Billy Mays was taking prescription painkillers Tramadol and hydrocodone for hip pain, but pill counts showed that Mays had taken the correct amount.
